DANIEL BBUHN, 0F HAMMOND, INDIANA.

COAL-CHUTE.

To all whom it may concern:

Be it known that I, DANIEL. BRUHN, a citizen of the United States,residing at Hammond, Lake county, Indiana, have invented certain new anduseful Improvements in- Coal-Chutes, of which the following is aspecification.

My invention relates to so called coal chutes which are in the form ofan iron frame which is inserted in anopening in a basement wall and isprovided with a cover, door or closer which may be opened only fromwithin and which door may also, when desired, contain a heavy glasswhich makes itserve as a window when not in service as a coal chute.

For practical purposes the questions of simplicity of construction andeven a small reduction in cost are important in connection with thesestructures owing to the quantities of same that are being used.

The objects of the present invention are to reduce the weight,the amountof metal required and the number of parts, and to obviate the use ofpivot lugs, friction-parts and the like at comparatively vital points inthe construction, so as to make the chute comparatively light inhandling and shipment, simple in the matter of installation, andcomparatively free from the liability of derangement.

With these objects in view the invention consists in the novelconstruction, combination and arrangement of parts hereinafter describedin detail, illustrated in the accompanying drawing and incorporated inthe appended claims.

In the drawing-Figure 1 is a vertical section through the chute and asection of building wall into which the chute has been inserted. Fig. 2is a similar view showing the door open and is substantially a sectiontaken on line22 of Fig. 8. Fig. 3 is a perspective view ofthe chutealone, open. Fig. 4 is a broken away detail view.- Fig. 5 is an enlargedsection taken substantially on line 55 of Fig. 1.

In the several views 2 represents the wall of a building in which hasbeen made an opening 3 for the reception of the chute which consists ofa rectangular, box-like framed having flanges 5, 6, 7 and 8 whichSpeeificationof Letters Patent."

serve as a frame around-the. chute-opening as seenfrom-the outside of.the building.

In the front portion of this openingor of the. frame 4 is pivoted thedoor 9. to'which are riveted segmental plates 10 and 11 which form sidesfor that portion of the chute which projects beyondthe exterior of thebuilding when the chute is open-as inFigs. 2and3. p U I As showniin Fig.1 the'door 9, when closed, is arranged to be within the vertical planeof the wall and of theopening frame consisting of the flanges 5, 6', 7and 8, which prevents water running downthe outer face of the wallfrom-entering within the chute. At the lower side of the opening underthe door the frame portion, 6 is provided with an inclined sill portion12 which is formed with an upward bulge,ridge5or bead 13 which extendsabove the lower edge of the door at its rear side and serves to preventwater running down the door from entering the inclined chute portionlhof the frame 4. At its lower edge the door 9 is provided with astiffening rib 15 the ends of which are bent over to form substantiallyround trunnions 16 and 17 which are journaled in openings 18 and 19inthe sides. of the frame 4:, said rib 15, as shown in Fig. 4:, beinghalfround in cross section and riveted to the door. A simple form of wallshield that is inexpensive .andmounted to insure strength and permanencyis provided in a plain rectangular plate of metal which is formed withlugs bent into loops or eyes 21 and 22 that rotatably engage a fixed rod23 riveted at its ends 24: and 25 into bores in the sides 10 and 11 intowhich said'ends fit snugly. This plain rod mounted in this fixed mannerobviates the usual unstable mountings for these shields and obviates theneed of special dies and parts which. are not even if these studs shouldaccidentally be broken off that would not in the least incapacitate ordisarrange the chute for working purposes, the construction beingdesigned throughout to obviate liability to accidental breakage in anyof the vital parts such as the mounting ofthe door, its pivotal supportsand the pivotal supports for the shield 20 designed to protect the wallof the building when coal is thrown into the chute. The lug or pin 27 isalso used as a part of a simple latch arrangement for locking the doorshut against being opened from the outside. On one of the vertical sidesof the frame 4 is secured in any suitable manner, as by rivets 28 and29, a bearing bar 30 on which is pivoted or fulcrumed at 31 a lever orhandle 32 in which is formed a notch 33 adapted to engage the pin orstud 27 the moment the door is in its vertical or closed position as inFig. 1. This lever is provided with an incline or beveled portion 34against which a stud 34 strikes in its rearward movement, thus raisingthe handle or lever so that it may be engaged with said pin. The releaseto open the door is efiected by simply raising the handle and pushingagainst the door from its rear or inside.

From the outer face of each side 10 and 11 projects a stud 34 for whichthere is room between said sides and the ends of the frame 4 tosubstantially the extent of the thickness shown in Fig. 5 of a narrowinturned flange 35 formed on each of the flanges 7 and 8. This flange 35is in each instance secured to 4 in Fig. 5, and side views of it areshown by dotted lines in Figs. 1 and 3 and partly in full lines in Figs.2 and 4. The vertical edges where the leader lines. from 35, 35 in Fig.5 strike also constitute stops for the stud or pin 34, thus simplifyingthe construction by doing away with special parts for that purpose. Onthe other hand, as will more fully appear hereinafter the stud 34 servesthe dual purpose of a stop on 10 or 11 engaging the flange 35 to limitthe outward drop or opening movement, as well as a part to be engaged bya latch to prevent opening of the door from the outside, the purposebeing to so coiirdinate and arrange the parts as to eliminate thecumbersomeness, expensiveness, lack of neatness, and complexityprevalent in devices heretofore produced for this purpose. This flange35 serves as a stop for the pin 34 and limits the outward drop of thedoor, and as in the other features of construction the flange is made toserve not only as the fastening means for the face flange 8 orpart ofthe outer frame but as a practicably indestructible stop for the pin 34which may be firmly and also unbreakably riveted into the side of themovable portion of the chute forming a part of the door. As the pin 34is between the side 1.0 or 11 and the vertical side of the frame 4 itoffers no obstruction within the chute and is not exposed to breakage bycoal being thrown against it. On the lower edge of the frame portion 5is a pair of lugs 36 and 37 against which the upper edge of the doorrests in its closed position and on the bar 30 is a lug 38 which limitsthe downward movement of the lever 32.

Having thus described my invention 1 claim as new and desire to secureby Letters Patent 1. In a coal chute, a frame adapted to be inserted ina wall-opening, a door having segmental sides secured thereto andforming the sides of the outwardly projecting portion of the chute whenopen, and a stifiening rib having a fiat side riveted to said door theends of which are bent upon themselves and form trunnions which arerevolubly mounted, in the sides of said frame.
